USB connected devices

Add option to load apps when a usb device is connected. IE for marshmallow, a DJI controller connected to phone works with Litchi app or DJI Go app, but to switch between apps to launch when connected I would have to clear the defualt app each time.

I have a dji p4 drone which requires the USB port to hook to the controller. I have 3 apps that respond to the event of plugging the controller into the USB. Once I choose which app it sets as default - To access the non default I must clear that app just like any app. To have BOW respond to the USB event would b wonderful.
